BACKGROUND:Wendy O. Koopa is the only female Koopaling in the family. She is rather spoilt, and her temper tantrums can shake the whole of Bowser's castle!
In most games, she shoots rings that she dubs "Candy Rings" which, despite their name, are not sweet like candy at all, but incredibly dangerous, so avoid them at all costs!
On a side note, no-one really knows what the O. in Wendy O. Koopa stands for. Wendy is the third boss in Super Mario Bros. 3 and was promoted to sixth in Super Mario World.
